tip on flying the SE. you want the ailerons on LOW rate they are real touchy. as for flying it. it likes to go slow. you can blast around at full power but the plane like to slow down and fly nose high.(you might need high rates for this to work well) I could fly mine (powered by a OS .50) at about a foot off the ground inverted for the length of the runway real slow.

when you get better with it you can up the control throws and move the CG back and it will do alot of the 3d stuff. I could hover mine with not too much problem and do stupid things like split-S's under 30 feet high. again a .40 might be a bit under powered for extreme stuff (might not hover it) but for flying around and getting used to a higher performance plane it should do OK

I traded mine in part for a Dazzler. Im begining to miss it might have to get a kit some other time.
